Students who kept wearing jeans without washing at all for 15 months

When wearing jeans, there is a method of wearing as it is without washing after buying it, wearing like wrinkles and rubbing along the body of the person and wearing it to fit it, but this way somehow I am concerned about hygiene, and some people are washing and wearing.

To solve such anxiety, a magnificent experiment was conducted to see if students at the University of Alberta in Canada went to jeans without washing for 15 months and see if they did not hurt their health. It seems that I was able to overcome the difficulties and to surprisingly find out the result while making an accident that an offensive odor is generated from jeans during the experiment.

The results of the experiment and the detection of bacteria from jeans are as follows.Student wears unwashed jeans for 15 months - thestar.com

Josh Le, a student at the University of Alberta in Canada, wore one skinny jeans without doing any washing for 15 months.Raw denimAs a way of dressing, there are things to keep wearing without washing, so that jeans can wear wrinkles and fades that fit perfectly with the contours of the body, but I have practiced that for a long time.

In pursuit of whether it really hurts his health by wearing dirty clothes, Ms. Le did not wash for 15 months and before washing the jeans that went on for the first time, how much bacteria are detected from the jeans As a result of inspection, there were many different kinds of bacteria detected from denim, but there was nothing like harm to health.

According to Professor Rachel McQueen specializing in human ecology, who cooperated with Ms. Le's experiment and worked on detection of bacteria from denim, the highest bacterial figures were recorded in the crotch of denim, It is said that 10,000 bacteria were found per square centimeter. On the contrary, the lowest figure was that it was part of the abdomen and buttocks of the denim. Colonies on denim were formed only by bacteria that always existed in the epidermis of human beings and did not contain things like Escherichia coli causing health hazards.

I rubbed the surface of the jeans with a thing like a cotton swab to collect deposits.


"I was really surprised, because I thought that bacteria would be explosively growing compared to before wearing, but as I found out that without having to wash jeans, there is no health problem I think that it has been proven that getting used to wearing jeans for a long time is not wrong, "Le says. Professor McQueen also said, "I believe that he was wearing denim under wearing underwear also affects this result."

Some of Le's friends seemed tired of the jeans experiment he was doing, According to Le, "Some people like to wear denim without washing and to get used to it, In other words, some people showed a strong refusal feeling ", and it seems that the surroundings were generally watching his experiment favorably.

Mr. Le seems to have tried his best efforts to keep the denim clean, but again it is difficult to keep paying attention for 15 months, he says that he spilled the food. In addition, he was wearing the same denim without fail even on a hot day.

During the experiment, he said that he was wearing the same denim for a total of 200 times or more and he said, "It seemed as if denim was ripe as it wore many times." However, around the age of seven months after I started wearing it, denim was unbearable enough during the experiment, but when I put it in my home freezer it means that it got completely stinky.

What surprised Professor McQueen more than anything to solve the problem of odor with such a rough technique was a result derived from additional experiments carried out after washing this jeans. After the denim was laundered, Mr. Le wore another 13 consecutive days and then detected the bacteria adhering to denim again, the result was almost the same as the content detected from the same denim for 15 months It was the same. In other words, the amount of bacteria remaining in jeans is almost unchanged in trying to wash once every 15 months, about once a week.


Although bacteria on the skin seems to be unlikely to harm young people who have resistance and physical strength, Professor McQueen says that at least once a month, rather than keeping on the same jeans without washing like Le, I recommend to do the laundry. It is because it is inevitable that the jeans smell, so that it causes uncomfortable surroundings.


It is problematic to keep wearing until it releases a stink as expected but there is a problem because it causes inconvenience to the surroundings, but it may be said that an excuse for wearing until jeans fit into the body can be made with this.

Mr. Le and Professor McQueen answer the interview and the movie reporting the result of the experiment can be seen from the following link.
